Description
The 4/3 A NiMH Battery with Tabs (4200mAh) is a high-capacity rechargeable battery cell designed for building custom battery packs, replacing compatible cells in existing rechargeable battery assemblies, and servicing specialized electronic equipment. Featuring nickel-metal hydride (NiMH) chemistry, this 4/3 A battery delivers a nominal voltage of 1.2 volts and a rated capacity of 4200mAh (4.2Ah), providing approximately 5.04 watt-hours of nominal energy. Its extended-length cylindrical design offers increased energy storage compared with many standard A-size rechargeable cells.
This 4/3 A NiMH rechargeable battery features factory-attached metal tabs designed for electrical connections during battery pack assembly. The 4/3 A format is approximately 17mm in diameter and 67mm in length, although actual dimensions and overall length including tabs depend on the manufacturer. The pre-attached tabs allow qualified battery pack technicians to connect compatible cells using appropriate joining methods, making this battery suitable for custom rechargeable power packs, emergency lighting battery assemblies, industrial electronic equipment, and specialized replacement battery systems.
Designed for repeated charging and discharging, the 4/3 A 4200mAh NiMH battery provides dependable rechargeable performance when used with a compatible charging system. This tabbed cell is intended primarily for battery pack construction and repair rather than direct installation into standard consumer battery compartments. Always verify the original battery chemistry, voltage, dimensions, capacity, tab arrangement, and charging requirements before replacing cells in an existing battery pack. This product includes one 4/3 A 1.2V 4200mAh NiMH rechargeable battery with factory-attached tabs.

Important Compatibility Note:
- BATTERY PACK APPLICATION: This 4/3 A NiMH battery features factory-attached tabs and is intended primarily for custom battery pack assembly and compatible battery pack repair.
- NOT A DROP-IN CONSUMER BATTERY: This tabbed cell is not designed for direct installation into standard AA, AAA, C, or D consumer battery compartments.
- DIMENSIONS: The 4/3 A battery format is approximately 17mm in diameter and 67mm in length, excluding tabs. Verify the exact dimensions of the supplied cell before installation.
- TAB CONFIGURATION: Confirm the position, orientation, length, width, and polarity of the factory-attached tabs before purchasing. Different tab arrangements may not be interchangeable.
- VOLTAGE: Each battery provides a nominal voltage of 1.2V. When multiple cells are connected in series, their nominal voltages add together.
- CAPACITY: Each cell is rated at 4200mAh. Connecting identical cells in series increases voltage but does not increase the pack's nominal amp-hour capacity.
- When designing a parallel battery assembly, appropriate cell matching, electrical protection, and pack engineering are required.
- Confirm that the original equipment or battery pack uses nickel-metal hydride chemistry. Do not substitute NiMH cells for NiCd, lithium-ion, LiFePO4, or other chemistries without manufacturer approval and a compatible charging system.
- Verify the original battery pack's total voltage, cell count, capacity, dimensions, wiring arrangement, and charging requirements before replacing individual cells.
- Battery pack assembly should be performed by qualified technicians using appropriate tools, insulation, and electrical connection methods.
- Use the factory-attached tabs for the intended connections. Avoid applying excessive heat directly to the battery casing or terminals.
- Do not attempt to weld, solder, or otherwise modify the bare battery casing unless the cell manufacturer specifically approves the procedure.
- Ensure that all electrical connections are properly insulated to prevent accidental short circuits.
- Use only matched cells of the same chemistry, capacity, age, and similar state of charge when assembling or repairing multi-cell battery packs.
- Do not mix new and heavily used cells in the same battery pack unless the equipment manufacturer specifically permits it.
- Use only a charger designed for NiMH battery packs with the correct total pack voltage and appropriate charge termination.
- Do not charge this battery using equipment intended exclusively for lithium-ion, LiFePO4, lead-acid, or other incompatible battery chemistries.
- For a 4200mAh battery, a 0.1C current corresponds to approximately 420mA. This is a general charging-rate reference, not a verified charging specification for this particular cell.
- Fast charging should only be used when permitted by the battery manufacturer and supported by the charging system.
- Actual battery capacity, discharge performance, and service life depend on operating temperature, discharge current, charging conditions, and battery age.
- Always verify positive (+) and negative (-) polarity before making electrical connections.
- Do not short-circuit, crush, puncture, disassemble, overheat, or expose the battery to fire.
- Do not use cells that are leaking, swollen, damaged, or showing signs of excessive heat.
- Keep batteries and unfinished battery assemblies away from children and pets.
- Store unused cells in a cool, dry location with their tabs protected against accidental electrical contact.
- Recycle spent NiMH batteries through an approved rechargeable battery recycling program.
